ELEVATOR.

Application filed July 25, 1927. Seriallto. 208,322.

This invention relates to elevators for carrying automobiles and has for an object the provision of means for utilizing the power of an automobile for raising and lowering the elevator.

Another object of the invention is the provision of means controlled by the direction of rotation of the drive wheelsof an automobile for controlling the direction of travel of the elevator, so thatwhen the wheels are driven in one direction the elevator will ascend, and when the wheels are driven in an opposite direction the elevator will descend.

Another obj ect of the invention is the pro vision of means for automatically stopping the operation of the elevator raising and lowering means when the elevator reaches a landing, the said automatic means also acting to disengage the drive wheels of the automobile from the elevator operating mechanism.

WVith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a sectional view showing an elevator constructed in accordance with the invention, the elevator being shown in lowered position.

Figure 2 is a similar view with parts broken away, the elevator being shown in raised position,

Figure 3 is a transverse sectional view with the elevator in the position shown in Fig ure 1. 1

Figure 4 is a bottom plan view of the elevator.

Referring to the drawings in detail where in like characters of reference denote corresponding parts, the elevator-comprises a platform 10, walls 11 and a top 12. The elevator may-be employed for carrying automobiles from one floor to another in a garage, or it may be employed for raising an automobile from a point below the ground to the ground,

and vice versa. In Fi ure 3, the reference character L indicates alower landing and U an upper landing which, as stated, may be landings at different floors in a garage, or, they ma be the landing of a grade and the landing elow a grade. If desired, steps may be provided for reaching the lower landing as indicated at S and these steps may be protected by a cover C which is hingedly secured to the top of the elevator as shown at 13. A door 1 1 provides entrance into the elevator from the steps, while a door 15 pro vides means for the passage of an auto1nobile into and out of the elevator.

Mounted in bearings 16 beneaththe plat form 10 is a shaft 17. This shaft is adapted to have wound thereon cables 18which pass around rollers 19 carried by the elevator and have their ends secured at the upper landing U as shown at 20.

Mounted in bearings carried by the platform and disposed transversely of the shaft 17. are spaced shafts 21 and 22. These shafts have secured thereon rollers 23 and 24 respectively which are adapted to be engaged by the drive wheels of an automobile, as shown in Figures 1, 2 and 3 of the drawings. The

shaft 21 is geared to the shaft 17 by means of a worm gearing 25, so that when the rollers direction to wind the cables upon the shaft and raise the elevator.

The shafts 21 and 22 respectively have mounted thereon drums 26 and 2T,while piv-.

otally mounted upon the elevator as shown at 23 is a member which provides a brake shoe 29 to engage the drum 26 and a brake shoe 30 to engage the drum 27. One end of this member is provided with a spring 31 and a spring 32 which are adapted to be engaged respectively by abutments 33 and 34. The

abutment 33 is located adjacent the lower landing and the abutment 34 located adjacent the upper landing.

lVhen the elevator is positioned at the upper landing U, the brake shoe 29 will ongage the drum 26 so as to hold the elevator at the landing and prevent rotation of the rollers 23. This engagement of the brake shoe 29 with the drum 26 is due to engagement of the spring arm 32 with the abutment 3 1.

After the automobile is positioned as indicated by the dotted lines in Figure 2 of the drawings, the drive wheels 20 will be rotated in the direction of the arrow in Figure 2 of the drawin s. This will cause the cables 18 to unwind'from the shaft 17 and permit the elevator to descend. As the elevator reaches the lower landing, the spring arm 31 will engage the abutment 33 so that the brake shoe 30 will engage the drum 2'? to stop rotation of the rollers 24. During the descent of the elevator neither of the brake shoes engage the drums. As soon as rotation of the rollers 2+1 is stopped, the automobile will ride oli' of the rollers due to the direction of rotation of the drive wheels IV.

Vhen it is desired to ascend, the drive wheels W are rotated in the direction of the arrow in Figure 1 of the drawings. This will rotate the shaft 17 in an opposite direction and windthe cables upon said shaft so that the elevator will ascend. lVhen the spring arm 32 reaches the abutment 34, the brake shoe 2!) will engage the drum 26 so that operation of the rollers 23 will be stopped and the automobile will ride olfof the rollers.

T he invention is susceptible of various changes-in its form, proportions and minor details of construction and the right is herein reserved to make such: changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. In an elevator, power transmitting means including elements carried by the elevator and adapted to be engaged by an automobile when the latter is on the ele ator platform to raise orlower the elevator through the operation of the automobile and means to automatically disengage said elements and automobile when the elevator reaches a land ing. s

2. In an elevator, power transmitting means including elements carried by the elevator and adapted to be engaged by an automobile when the latter is on the elevator platform to raise or lower the elevator through the operationof the automobile and means to automatically disengage said elements and automobile when the elevator reaches a landing, said ineans'also acting to stop the elevator.

3. In an elevator, power transmitting means including elements carried by the elevator and adapted to be engaged by an automobile when the latter is on the elevator platform to raise orlower the elevator through the operation of the automobile, a brake mechanism carried by the elevator, and means 10- cated at the elevator landing to engage the brake mechanism and apply the brake and release the elevator carried elements from the automobile.

4-. In an elevator, a shaft carried by the elevator, cables wound upon the shaft and adapted to raise or lower the elevator when the shaft is rotated, spaced. shafts carried by the elevator and disposed at right angles to the cable wound shaft, gearing connecting one of the spaced shafts with the cable wound shaft, means carried by the spaced shafts for engagement by the wheels of an automobile to drive said shafts and operate the cable wound shaft and means operable when the elevator reaches a landing to cause the drive wheels of the automobile to disengage the spaced shaft carried means and to provide a brake to stop the operation of the cable wound shaft.

5. In an elevator, a shaft carried by the elevator, cables wound upon the shaft and adapted to raise or lower the elevator when the shaft is rotated, spaced shafts carried by the elevator and disposed at right angles to the cable wound shaft, gearing connecting one of the spaced shafts with the cable wound shaft, means carried by the spaced shafts for engagement by the wheels of an automobile todrive said spaced shafts and rotate the cable wound shaft in accordame with the direction of rotation of said drive wheels and means operable when the elevator reaches a landing to cause the drive wheels of the automobile to disengage the spaced shaft carried means and provide a brake to stop the opera tion of the cable wound shaft.

(5. In an elevator, a shaft carried by the elevator, cables wound upon the shaft and adapted to raise or lower the elevator when i the shaft is rotated, spaced shafts carried by the elevator and disposed at right angles to the cable wound shaft, gearing connecting one of the spaced shafts with the cable wound shaft, means carried by the spaced shafts for engagement by the wheels of an automobile to drive said shafts and operate the cable wound shaft, a brake drum carried by each of the spaced shafts, a brake shoe adapted to engage each drum and means to actuate the brake shoes in accordance with the direction of travel of the elevator to selectively engage the brake drums.

In testimony whereof I affix my signature.

ALFRED NORDLAND.
